Question Copper or Nickel IHS for my i5-9600k

[Indivision]

Hi guys, I am overclocking enthusiast, as I did OC my 9600k stable to 5.1 with full nickel CPU block from EKWB, but my temps are not great as I get 80 C degrees in gaming. So I am considering to delid my CPU , as I have the tool and etc, but also I am considering of buying new IHS, but i cannot decide which one is better and does it really worth. As I see the Nickel one is smaller, but I am not aware of how good it perform, when the copper one is much bigger which will spread the heat better. Please suggest me something, share your knowledge !

Not seeing that first one as all that different from the stock IHS. A little smoother perhaps.

The Intel one is nickel plated copper as well, so the all copper one isn't all that different. I don't really like seeing the machine marks, it really depends on how flat it really is, and how flat the cooler you want to put on it is.

You might simply test your IHS for flatness when you get it off by spinning it upside down on a flat surface. If it spins easily it is convex and could do with some lapping.

The real gains from delidding are reducing the gap between the IHS and the die, not so much the thermal material or IHS material.
